MECHANICAL WINDOW OPERATOR.

Application filed January 2, 1924. Serial No. 683,872.

new and useful Improvements in Mechanical Vindow Operators, of which the following is a'specification.

This invention relates to an improved means for operating the sashes of a multisash window, particularly of the swinging sash type.

The primary object of the invention is to provide a simple, compact and eflici'ent means whereby through manipulation of a crank located at a convenient point on the window frame, the sashes of a multi-sash window may be moved into and out of open position as desired.

A further object of the invention is to provide operating means of the character described with which it is possible to selec-- tively operate the sashes so that one sash may be opened to a greater extent than the other or in fact, operated entirely independent of theother.

With the above .mentionedand other objects in view, the invention consists inthe novel construction and combination of parts,

hereinafter described, illustrated in' the accompanying drawings, and set forth in the claims hereto appended, it being under-i stood that various changes in the form, proportion, size and minor details of construction within the scope of the claims may be resorted to without departing from the spirit or sacrificing any of the advantages of theinvention. I I

Referring to the drawings: p

Fig. 1 represents a fragmentary vertical sectional view through a multi-sash window showing the mechanism of my invention as applied thereto.

F ig.'2 represents a front elevation of the face plate.

Fig; 3 represents a rear elevation of said face plate showing part of the mechanism associated therewith.

Fig. 4 represents a vertical sectional view of the operating mechanism of the invention showing parts broken away and in elevation. V

Fig. 5 represents an enlarged fragmentary sectional view with part shown in side elevation of the operating mechanism.

In the embodiment of the invention illustrated in the accompanying drawings, 1 designates a window frame having a plurality of sashes 2 and 3 mounted therein so as to be swung into and out of openposition. The sashes are mounted on links 4 which are pivoted on slide members vertically slidably mounted in guides 6 on the frame 1, the other ends of the links are pivoted as at '7 to the sides of the sashes between the upper and lower ends thereof. EX- tending from the upper endsv of the sashes o the sides thereof are levers S to which levers the mechanism of my invention is connected, said mechanism being generally designated 9 and adapted as shown in Fig. 1, to be mounted on frame.

The mechanisnr9 comprises a frame-like V casing 10 extend1ng through which is a tubular shaft 11. On the shaft 11 is a pinion 12 which is adapted to be moved on shifting of the shaft into and out of engagement with rack bars 13 and 1 1, which latterextend vertically through the casing and up and into a vertical compartment 15 formed in one side of the window frame. The upper ends of these rack bars are connected by links 16 with the free ends of the levers 8 so that on vertical movement of the rack bar, the sashes will be mofied, there beingone rack bar for each sas The rack bars slide between guides 17 carried on the casing 10. One of the rack bars is engagedon its outer side by a plate 18 which is yieldingly urged into engagement with the rack bar by a leaf spring 19 fastened to the casing 10.. This arrangement provides for holding the rack bars against rattling and in adjusted position, and insures a smooth operation of the mechanism. The shaft 11 extends out through a face plate 20, which plate is fastened to the inner face of one side of the window frame as shown inFig. '1; Provision is'inade for holding the shaft in adjusted position to maintain the pinion in engagement with either one ofthe rack bars, through use of a lock plate 21, which is carried on the rear side of the face plate 20 and pivoted at its upper end, as at-22, to said plate. The lock plate 21 isformed with a central opening 23 through which the shaft 11 extends.- The shaft is provided with circumferential grooves 2st in which the edges of the plate one side of the window 21 around the opening, are adapted to be engaged'to hold theshaft in adjusted position. A leaf spring 25 associated with the upper end of the plate 21 and engaging 'a projection 26 on the*'pla-te*f20 extremes a force such as will at all times maintain the plate with the opening 23 inan eccentric relation to the opening in the face plate. The lower end of the plate 21 'is provided with a finger'piece 27 which extends out through on opening 28 formed in the plate 20. On moving the finger piece in the opening 28, the member 21 will be rocked so that the opening 23 therein will be moved to aline with the opening in the face plate and cause the shaft tobe released whereupon the shaft may be adjusted as desired. On release of the finger piece 2'7, the member 21 will be moved by the spring 25 so as to engage in one of the grooves 24 and lock theshaft in adjusted position; I

A crank 29 is employed to rotate the shaft 11 and its stem 30 is-adapted to be extended into the tubular shaft 24L. A projection-31 on thestem is adaptedto engage in a bayonet slot 32 provided in the shaft. hen the stem of the crank is extended'into the tubularshaft, it engages a spring urged plunger 33 provided at the-inner end of the tubular shaft. This causes the projection to besecurely held in the bayonet slot. When the crank is removed, a cover plate 3 pivoted on the face plate 20, is swung into position to cover the opening through which'the shaft extends, sa-id'shaft being first moved into its innermost position to permit of the movement of the cover plate.

,The mechanism of the invention having been installed in connection with a window.

as shown, may be readily operated byturning the crank 29 to open 'or close the sashes,

the operation being selective. then it 'is desired, for example to open the upper sash with thelower sash remaining closed, the operator after mounting the crank in place presses the finger piece 27 to one side so as to releasethe lock plate-'21 and: thenpulls out on the crank "so asto cause the shaft 11 to slide outwardly'and bring the pinion l2 -into mesh with the teeth onthe rack bar 13' Upon turning the crank so as to rotate-the shaft in acounter-clockwise direction, the rack bar 13 willbe moved downwardly and through the link 16 and lever 8, swing the uppersash3 into open position, the extent of movement" of said saslr being dependent on the extent of rotation oftheshaft. T he operator may in this way open the sash'to the extent-desired. l hefifriction set up by the spring pressed guides 17 'on the rack bars is sufficient to hold the sashes in position into wh ch it hasbeen movedl To open the lower sash, the shaft 1 1;; is again adjusted as desired so -as to bring the pinion l'2 'into engagement with the other rack bar and the the casing with which said rack bars eng operation is repeated. Obviously the crank is operated in the reverse direction in order to close the windows. As the pinion may be moved into engagement with either rack b'arjth' m eehani's' in is selective and may be operated to quickly and easily control the movement of'anyone of several sashes. The entire mechanism may be easily encased in the'frame of awi'ndow so that it is practically hidden when assembled for useand pre sents a neat appearance. The "inechanisiii' of the invention.may beemplo yed to great advantage in connection with wingin 'sash windows in which two or more sashes are employed and the upper of the sashes are out of reach with respect to the floor. "It is obvious the mechanism may be adapted for operating as many sashes as desired, it only being necessary to increase the number of rack bars.
